Chinese scientific ship ends mission in Nigeria
LAGOS - Chinese scientific research ship Dayang Yihao, or Ocean One, on Wednesday successfully ended its nine-day exploration and research mission in Nigeria's waters with Nigerian and Chinese scientists. The ship, on it 1st Sino-Nigeria Joint Cruise, safely returned to the Apapa Harbor in Lagos, Nigeria's commercial hub, at 10:45 am, local time with hundreds of Nigerians and Chinese from all walks of life trooped to the port to welcome the crew. The team, consisting of 81 crew from both sides conducted research mainly on the western part of Nigerian waters, Captain Cao Yezheng told Xinhua. "We have six Nigerian navy personnel, nine Nigerian scientists and 66 Chinese crew on board and comprehensive oceanic survey were conducted," he added. "We were able to understand the water chemistry, understand the sea channel, the fishery condition and some other areas that needed to be touched," Cao said. Speaking at a brief reception, Dr. Liu Xianfa, consul general of China in Lagos, said China is pleased to the fact that the Sino- Nigeria cooperation has been fruitful in critical areas of life. "The prospects of the Chinese-Nigerian relations are bright," he added. Also speaking, Emmanuel A. Ajao, the acting executive director of Nigerian Institute of Oceanography and Marine Research (NIOMR) said the successful scientific joint research program will benefit both of the two countries and the world. In his address, Chen Lianzeng, the vice administrator for State Oceanic Administration (SOA) of China, who led a nine man delegation from Beijing, to witness the arrival of the research team, said this exercise will promote development and cooperation in other areas of marine science and technology between both countries. He told the gathering that the exercise will further add value to the Nigerian side, noting that it will continue to promote and strengthen the existing friendly relations between Nigerian and China. Chinese defense attache in Nigeria, Senior Col. Kang Honglin, oversea Chinese, officials from the Lagos government, Nigerian Navy, Nigerian Port Authority, Nigerian Institute for Oceanography and Marine Research (NIOMR) and Nigerian press also attended the reception on Wednesday, including the representative of the Honourable Minister of Agriculture, Dr. Akinwumi Adesina. Dayang Yihao is the only open-ocean going vessel designated and equipped for deep-sea research in China.
Chinese research ship to set sail on global voyage
QINGDAO - The Chinese scientific research ship Dayang Yihao, or Ocean One, is expected to set sail on a new global voyage on April 18, the country's oceanic authority said Friday. The 380-day global trip will take the ship across the Atlantic and Indian oceans, said a spokesman with the Second Institute of Oceanography under the State Oceanic Administration. The voyage, the 26th of its kind, will focus on research on polymetallic sulphides resources and biological resources in relevant areas, the spokesman said. Dayang Yihao will carry advanced scientific instruments, including a remotely-operated underwater vehicle, he said. It is not yet known how many scientists will participate in the scientific expedition, which will start from Sanya in South China's Hainan province. On December 11 last year, Dayang Yihao completed a 369-day scientific research mission that covered more than 64,000 nautical miles, or about three times the length of the equator. The global trip took it across the Pacific, Atlantic and Indian oceans.
Sub vessel to attempt record-setting dive
BEIJING - High underwater pressure will be the greatest danger that Jiaolong, China's manned deep-sea vessel, will contend with when it attempts to make the deepest dive on record this year, a senior official said. "Jiaolong will make a 7,000-meter test dive this year after several improvements are made to the submersible vessel," Jin Jiancai, secretary-general of the China Ocean Mineral Resources Research and Development Association, said over the weekend. Before attempting the record-breaking dive, the vessel will make a roughly 3,000-meter test dive in the South China Sea in March or April, he said. He did not say when the 7,000-meter dive is to take place. Underwater, pressure increases at the rate of one atmosphere for every 10 meters of depth. One atmosphere is equal to about 10 metric tons of force per square meter. If the planned dive is successful, Jiaolong will have proven itself capable of reaching nearly any seabed in the world. China will also hold the record for performing the deepest dive, surpassing Japan, whose Shinkai 6500 dove 6,527 meters in August 1989. Jiaolong - designed to reach a maximum depth of 7,000 meters - carried three people to 5,188 meters below sea level in a test dive in international waters in the northeastern Pacific Ocean last year, indicating the vessel is capable of reaching more than 70 percent of the planet's seabeds. "If Jiaolong succeeds in the 7,000-meter dive, the vessel will play an important role in future scientific research and mineral exploration in the deep sea," said Tao Chunhui, professor of the Second Institute of Oceanography and chief scientist on the Chinese scientific research ship Dayang Yihao, or Ocean No 1. According to the 12th Five-Year Plan (2011-15) released by the State Oceanic Administration on Friday, China is working faster to build both a ship that will take deep-sea vessels to dive sites and another vessel that will conduct scientific research in the ocean and explore the underwater world. Over the next 20 years, China will push its technical capabilities to catch up with advanced nations in conducting deep-sea research. Scientists say the ocean floor contains rich deposits of a range of potentially valuable minerals, but the extreme depths pose obstacles to gathering them. Last year, China became the first country approved by the International Seabed Authority to look for polymetallic sulphide deposits, a recently discovered mineral source, in the Southwest Indian Ridge, a tectonic plate boundary on the floor of the Indian Ocean. In 2001, the China Ocean Mineral Resources Research and Development Association signed a 15-year contract with the seabed authority to search 150,000 square kilometers of seabed for polymetallic nodules, small rocks containing metal ore.

3 In March, the manned deep-sea submersible Jiaolong finished a 118-day exploratory voyage in the Indian Ocean, while the research ship Dayang Yihao was also on a mission in the area. It was the first time two major Chinese oceanic research facilities had worked in the Indian Ocean at the same time.
